Abstract
Aqueous free-flowing surfactant compositions having non-Newtonian shear thinning properties are disclosed. These stable compositions include both cationic and anionic surfactants and can suspend water-insoluble particles or partially insoluble components.
Claims45
An aqueous free flowing composition comprising:
- (a) at least one anionic surfactant comprising an alkyl sulfate or alkyl ether sulfate;
- (b) at least one cationic surfactant comprising a quaternary ammonium compound having four substituent groups selected from the group consisting of hydrocarbons and hydrogen, wherein at least one of the groups is a hydrocarbon;
- and
- (c) water,
- wherein the at least one anionic surfactant and the at least one cationic surfactant are present in a combined amount such that the composition possesses non-Newtonian shear thinning properties and a stable viscosity under at least one freeze/thaw cycle.
